AWEAR Studies: Data Checker

This notebook was written for the AWEAR Case Studies as part of a PhD project on Engineering Systems Design in Healthcare at the Engineering Systems Division, DTU Management, in collaboration with Rigshospitalet-Glostrup.

The purpose of this notebook is to provide regular reports on the data being recorded from study participants, to check that it is being recorded and looks as expected. The R script imports, tests and plots data from a specified participant and timeframe, as shown in the code and output below.

Report subject and period:

This report is for user  P13NB for the time period from  2018-04-25  to  2018-05-09

Import and restructure data:

Overview of available csv files and their current use status:

File	Description	Status

“battery.csv”	charging log	in use
“bluetooth.csv”	-	not in use
“calllog.csv”	log of phonecalls	not in use
“experience_sampling.csv”	answers to daily self-reports	in use
“hardware_info.csv”	-	not in use
“location.csv”	GPS data from watch and phone	in use
“screen.csv”	screen on/off transitions (phone)	in use
“sms.csv”	sms log	not in use
“step_count.csv”	step counts from watch and phone	in use
“wearable.csv”	-	no longer in use
“wifi.csv”	-	not in use
